@Enkidoh: Lest we forget the flower from Ul'dah, the balloonfish from Limsa Lominsa, and the treent vine from Gridania in the 1.0 story lines... we did get those in a echo hop. There was also the pistol from the Coral Tower that we lost inside an Echo hop. The Echo seems to be different from what it was in 1.0, but that's just because we've not gotten an interactive hop yet. Minfilia did give what seems to be the exact same speech about the echo that she did in the Path of the Twelve when we first joined them.
But then again all of the above is from the 1.0 main scenario and I'm not really sure how much of that was retcon'd

It could be the echo... if the echo is unchanged from 1.0 it gives the narrowest of narrow possibilities...
and the looks of what happened with Cid's Goggles doesn't look similar to an echo hop...

I'm only going by my memory here, maybe the Loremongers can give a more definitive answer
